Struct rusty_v8::Function

#[repr(C)]
pub struct Function(_);

A JavaScript function object (ECMA-262, 15.3).

Methods

impl Function

pub fn new<'sc>(
    scope: &mut impl ToLocal<'sc>,
    context: Local<Context>,
    callback: impl MapFnTo<FunctionCallback>
) -> Option<Local<'sc, Function>>

Create a function in the current execution context for a given FunctionCallback.

pub fn call<'sc>(
    &mut self,
    scope: &mut impl ToLocal<'sc>,
    context: Local<Context>,
    recv: Local<Value>,
    arc: i32,
    argv: Vec<Local<Value>>
) -> Option<Local<'sc, Value>>

Methods from Deref<Target = Object>

pub fn set(
    &self,
    context: Local<Context>,
    key: Local<Value>,
    value: Local<Value>
) -> MaybeBool

Set only return Just(true) or Empty(), so if it should never fail, use result.Check().

pub fn create_data_property(
    &self,
    context: Local<Context>,
    key: Local<Name>,
    value: Local<Value>
) -> MaybeBool

Implements CreateDataProperty (ECMA-262, 7.3.4).

Defines a configurable, writable, enumerable property with the given value on the object unless the property already exists and is not configurable or the object is not extensible.

Returns true on success.

pub fn get<'a>(
    &self,
    scope: &mut impl ToLocal<'a>,
    context: Local<Context>,
    key: Local<Value>
) -> Option<Local<'a, Value>>

pub fn get_identity_hash(&self) -> int

Returns the identity hash for this object. The current implementation uses a hidden property on the object to store the identity hash.

The return value will never be 0. Also, it is not guaranteed to be unique.

Trait Implementations

impl Deref for Function

type Target = Object

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
